GROVEVILLE, NEW JERSEY, A CORPORATION OF NEW DYEING MACHINE.

Application filed December 22, 1922. Serial No. 608,532.

To all whom it may comer n:-

Be it known that 1, Jaime H. Tiroinrso v, a citizen of the UnitedStates, residing in Trenton, Mercer County, New Jerse have inventedcertain Improvements in yeing Machines, of which the following 1s aspecification.

My invention relates to certain unprovements in dyeing machines, inwhich the liquor is circulated in the vat by propellers at one endthereof, first in one direction, and then in the opposite direction.

One obj ect of the invention is to construct the dyeing machine so thatthe worsted tops, or balls, can be perfectly dyed. A further ob ect ofthe invention is to construct the dyeing machine so that a number ofcages can be used with a. single vat to allow the tops, or balls, to belocated-properly in the cages prior to their insertion in the vat.

A still further object of the invention is to provide means forpreventing the liquor in circulation flowing around the cages.

These ob'ects I attain in the following manner, re erenoe to theaccompanying drawings, in which: I

Fig. 1 is a sectional perspective view of the vat, showing the cageelevated and th cover for the e removed;

Fig. 2 is a longitudinal sectional view through one end of the dyeingmachine illustrating my invention;

Fig. 3 is a. transverse sectional view;

Fig. 4 is a transverse sectional view of a portion of the vat and cage;and

Fig. 5 is a perspective view of one of the worsted tops, or balls.

Referring to the drawings, 1 is the vat. At one end of the vat is apartition 2, stopping short of the top and bottom of the vat to allowfor the free circulation of the dye liquor. 3 is the dyeing compartmentand 4 is the circulating compartment, in which is a horizontal partition5 having one, or more openings, in which are mounted the circulatingpropellers 6. Each circulating propeller is secured to a shaft 7 drivenby mechanism, not shown, and which is common to this class of dyeingmachines.

In the lower portion of thedyeing compartment 3 is a supporting rail 8,extending on all four sides of the compartment. At the partition end ofthe vat, the rail extends over a circulating passage 9, which forms aprovided with center braces 16.

continuation of the passage 10 under the partition '2. In the uppersurface of the rail 8 is a 1groove 11 having beveled sides, as shown inigs. 2 and 3, to receive the lower edge 12 of a cage 13. The lower edgeof the cage is tapered to correspond with the taper of the walls of thegroove so as to prevent the passage of liquor between the cage and thebody of the vat and also to provide a firm support for the cage.

The sides of the cage 13 are solid, as shown in Fig. 1. The cage hascorner braces 14 and guide strips 15, and is also referably he bottom ofthe cage is made of a series of transverse slats 17, resting betweenside strips 18 and 19 and spaced apart by pins 20 set in sockets in thestrips 18 and 19, Fig. 3. When the cage is of considerable width,central strips 18 and 19*, with spacing pins 20*, may be used, as insaid Fig. 3. The strips 18 and 19 are firmly secured to the sides 21 ofthe cage 13. The upper portion of the cage is open, as shown in Fig. 1,so as to allow the tops, or balls, to be placed properly therein.

22 designates the cover for the cage and consists of a frame 23 andtransverse slats 24 resting between strips 25 and 26 secured to theframe and spaced apart by pins 27, Fig. 3. 25 and 26 designate central,reinforcing strips for the slats having spacing pins 27*. Extendingacross the cover 22 are bars 28 securely bolted to the frame 23 andattached to the bars 29, which extend through beams 30 and are providedwith wing nuts 31, and nuts 32, the latter being located under thebeams. By turning the nuts, the cover can be raised,-or'lowered.

Secured to the sides of the cage 13 are plates 33 having threaded stems34 at their upper ends, which extend throughholes 35 in the ends of thebeams 30. The plateshave seats for the beams 30 so that, when they aresecured in position by nuts, the cage is' firmly attached to the beams,and, when the beams rest on the edges of the vat, the cage is in properposition in the vat, as shown 1n The cover 22 snugly fits the cage sothat the liquor must circulate between the slats and through thematerial in the cage.

In Fig. 5 is illustrated one of the Worsted tops, or balls, which can bedyed successfully in my improved dyeing machine. The tops,

or ballsi, are placed in the cage 13, when it is out of the vat, in themanner shown by dotted lines in Fig. 2. These balls may vary in size.They may be placed in the cage in 'an upri ht position, or on edge. Theymay also be placedin a single row, or in two rows, as described. Thecover of thecage is preferably adjusted so that there, is a lay of threeor four inches between the alls and the slats.

The cage is loaded with balls at one side of the vat and the cover isadjusted in position, after which the cage is raised by a hoist, thehooks of which engage the eyes 36 on the beams 30, and, when in positionabove the vat, the cage is lowered into the vat and the beams aresecured in position, as shown in Fig. 4. Then the dye liquor iscirculated-first in one direction and then in the opposite direction.The liquor penetrates the balls of combed wool and the wool isthoroughly dyed. When the dyeing is completed, the cage is removed fromthe vat and another loaded ca e is placed in position. The cage of dyeballs can be carried to a washing, or scouring, vat, if desired.

I claim: 2

1. The combination in a dyeing machine, of a vat; means for circulatingdye liquor in the vat; beams resting on the edges of the vat; a cagesuspended from the beams and within the vat; and a cover for the cage,also carried by the beams.

2. The combination in a dyeing machine, of a vat; means for circulatingdye liquor in the vat; beams resting on the vat; a cage suspended fromthe beams and within the vat; a cover for the cage; and adjustable meansconnecting the cover to the beams.

3. The combination in a dyeing machine, of a vat; a partition in the vatforming a dyeing compartment and a clrculating compartment; means forcirculating the dye liquor inthe vat; a grooved rail at the bottom ofthe dyeing compartment; and a cage having a lower edge extending intothe groove of the rail.

4. The combination in a dyeing machine, of a vat; a partition at one endof the vat which divides the vat into a dyeing compartment and a.circulating compartment;

a rail at the bottom edge of the dyeing comnear one end of the vatforming a dyeing compartment and a circulating compartment, saidpartition stopping short of the top and bottom of the vat to allowliquor to circulate over and under the partition; a rail at the bottomedge of the vat, the section of the rail at the partition having apassage therein communicating with the space under the partition; a cagelocated in the dyeing compartment, said cage resting on the rail,

the cage having a slatted bottom; and a slatted cover for thecage.
